Venn diagrams displaying the partial overlap of m/z ion features present in tomato leaves, deemed statistically significant and positively correlated to the flagellin-derived elicitor treatments. The features were selected from the OPLS-DA models generated from the 16 h (blue), 24 h (purple) and 32 h (orange) individual datasets comparing the Flg22 (Flg) and FlgII-28 (FlgII) treatments with the MgSO₄ control. The numerical values depict the metabolite features (listed in Table 1) that are unique to the Flg22 vs. FlgII-28 treatments over the time intervals, and conversely, that overlap in the treatments
